1 Two integer clusters share fetch and decode logic but have their own dedicated Instruction and Data cache
2 Integer clusters can not be shared between threads: integer cores act like a Chip Multi Processing (CMP) CPU.
3 The extra integer core (schedulers, D-cache and pipelines) adds only 5% die space
4 L1-caches are similar to Barcelona/Shanghai (64 KB 2-way? Not confirmed)
5 Up to 4 modules share a L3-cache and Northbridge
6 Two times 4 Bulldozer modules (2 x 8 "cores" or 16 cores) are about 60 to 80% faster than the twelve core Opteron 6100 CPU in SPECInt_rate.
文中提到多增加一個整數核心面積才增加5%!!那AMD乾脆做個八個整數核心算了
5X8才40%不是很好嗎?!
